A 155-MHz BiCMOS automatic gain control amplifier

This paper proposes a 155-MHz automatic gain control (AGC) amplifier implemented in a double-poly-double-metal 1.0-/spl mu/m BiCMOS technology. The amplifier contains an exponential-type variable gain amplifier, a buffer-based filter, and asynchronous demodulation peak detector circuits. The initialization and the output magnitude setup circuits are incorporated in the AGC amplifier. It yields an input dynamic range of at least 26 dB and provides a constant output of 1 V/sub pp/ at a 50-/spl Omega/ load with AGC loop bandwidth of 80 kHz. The power consumption is 180 mW from a single 5-V supply.
